The pop star quietly made a donation to help Aaron Van Riper's family with its mounting medical bills.

On Saturday, Texas volunteer firefighter Aaron Van Riper responded to a 911 call regarding a car crash when he made a heartbreaking discovery: The victims in the accident were his own wife, Amber, and his son; the boy has been released from the hospital and Van Riper's wife, Amber, remains there, per the local ABC affiliate.

The heartbreaking incident quickly gained national attention, and a friend of the family set up a GoFundMe account for the family's mounting medical bills. On Wednesday night, a donation for $15,000 was left for the family, which was signed "Taylor Swift." (Billboard has confirmed it's actually the singer).

There have been more than 2,000 separate donations so far, so it seems like Swift has helped jump-start a worthy new trend.
